My apologies that I haven’t yet posted details about pre-ordering the  new Fryer/Di Marco Treble Booster. I have been delayed working on some other urgent things, been working hard burning the midnight oil! Very soon I expect that the details will be finalised so that pre-order details can be posted.

Today I was at the graphic art studio and we were doing artwork mockups for the new pedal’s screenprinting. Below are photos of things we experimented with. At times we compared the new artwork with some of my great older pedals such as the Brian May/Fryer Treble Booster Touring from 2008.

Hooroo, Greg


2nd February 2023:

Happy New Year to all, and an update about the new treble booster. Due to various things late last year its unfortunately taken me longer than anticipated to get the new prototypes completed and shipped off to Marco Giuseppe Di Marco in Italy for his appraisal.

2 of the latest prototypes were posted earlier this week and hopefully Marco will have them for testing in another 2 weeks. At the moment the project is kind of ‘on hold’ until we discuss things further after Marco uses the new prototypes live on stage and compares them to the original pedal.

The ‘Fryer/Di Marco Treble Booster’ is based on a prototype which I recently made for Marco Giuseppe Di Marco from Italy.

Marco uses the new booster mounted on his guitar strap, along with a Shure wireless unit. He is currently touring in Europe with his band “Queen On Fire”.

This short video is from soundcheck on 12th August 2022. Marco describes the new treble booster and gives a quick rundown of his rig:

Marco’s prototype pedal uses my Treble Booster Touring circuit with a few custom touches. It has a handmade pcb which has a different layout to the standard TB Touring pedal, it also has a hand selected/tested transistor which is a little more powerful than usual, plus selected components and a few other nice handmade things.

The pedal uses a lightweight diecast aluminium box which is also suitable for mounting on a guitar strap.

I hope to have more photos, soundfiles and comments from Marco Giuseppe Di Marco to post soon.
